Two silks of the same color are tied together at one of their diagonal corners and given to a lady assistant to hold in her cupped hands such that the other two diagonal corners hang outside. A third silk of a different color is vanished. When the silks in the assistant's hands are pulled apart, the vanished silk appears between them, transformed into a colorful panty. Naturally, due to the materials involved in this magic, it is unsuitable for children's party.
